The problem showed up when i moved folders with cache to my ntfs drive and made symbolic links to it (don't quite remember exact locations of them /var/cache , /var/tmp I guess also /home/roman/.cache and so on)
When i restarted the system it booted in terminal (didnt start desktop environment)
I thought that its becouse my ntfs drive is not mounting at the startup so i mounted it to the same place as it was mounting before used sudo mount /dev/sda1 /media/roman/R (and i succeed because i entered to the folder cd /var/cache which i could not enter when it was not mounted)
Than i used startx command thought it going to start but it didnt !
Any suggestions to a noob user ?
